Coffee linked to lower risk of liver cancer and fatal cirrhosis

Coffee lovers may get another reason to savor their morning cup: a large new analysis suggests regular coffee consumption is linked with significantly lower risks of cirrhosis, liver cancer, and death from liver disease. Researchers examined decades of health records from a half-million adults and found consistent patterns that point to potential liver benefits—beyond the buzz.

This study builds on a growing body of research connecting coffee to better outcomes across multiple conditions. Investigators from Cedars-Sinai and data from the UK Biobank were central to the findings, which also include biochemical signals that strengthen the case for a protective effect.

What the new study examined and where the data came from

The analysis used the UK Biobank, a vast health database that has tracked roughly 500,000 people ages 40–69 over many years. That resource contains detailed lifestyle information, medical diagnoses, and blood biomarkers, and has supported thousands of peer-reviewed studies.

Researchers from Cedars-Sinai—led by assistant professor Hyunseok Kim and colleagues Shelly Lu and Ju Dong Yang—focused on three liver-related outcomes:

• cirrhosis (severe scarring of the liver),
• primary liver cancer (hepatocellular carcinoma), and
• death attributed to liver disease.

Clear reductions in liver disease risk tied to coffee drinking

The team compared people who reported drinking coffee with those who did not. After adjusting for many factors, the analysis found notable associations between coffee intake and lower liver risks. Key findings included:

• 32% lower risk of cirrhosis among coffee drinkers versus non-drinkers.
• 47% lower risk of developing liver cancer in those who consumed coffee.
• 42% lower risk of liver-related death tied to coffee consumption.

These reductions were large enough to be meaningful at the population level and mirror earlier signals seen in other cohorts.

Blood proteins and decaf: clues about how coffee may protect the liver

To go beyond simple associations, researchers also analyzed blood protein levels. Coffee drinkers tended to have higher concentrations of proteins linked to healthy liver function, making a casual correlation less likely and suggesting a biological connection.

Interestingly, the study found that the pattern of benefit was observed even among consumers of decaffeinated coffee at higher intakes. This points toward the role of coffee compounds such as flavonoids and phenolic acids—rather than caffeine alone—in supporting liver health.

How these results fit with previous research and public health context

Past large-scale work has similarly hinted that coffee may be protective for the liver. For example, an earlier UK Biobank analysis reported:

• about a 21% lower risk of chronic liver disease,
• roughly a 20% lower chance of fatty liver disease, and
• near a 49% reduction in death from chronic liver conditions for coffee drinkers compared with non-drinkers.

Public health positions have shifted over time: the World Health Organization removed coffee from its list of possible carcinogens in 2016 after accumulating evidence that it is not harmful and may even offer health benefits.

Expert guidance and practical considerations for coffee drinkers

The investigators emphasized moderation and individual tolerance. They suggested that people who already enjoy coffee and tolerate it well may consider it a reasonable part of their diet, but they stopped short of recommending that non-drinkers start drinking coffee solely for liver protection.

Doctors continue to stress established prevention strategies for liver disease, including:

• maintaining a healthy weight,
• limiting alcohol intake,
• regular physical activity, and
• managing blood sugar, blood pressure, and cholesterol.

Not everyone can tolerate multiple daily cups—sensitivity to caffeine causes jitters, sleep disruption, or palpitations in some people—and for those individuals, decaf may show similar associations at higher consumption levels according to the study.

Questions that remain and directions for future research

While the associations are compelling, observational analyses cannot fully prove causation. Additional research is needed to identify the specific coffee components and biological mechanisms responsible for the effects, and to determine optimal serving sizes and preparation methods.

Ongoing studies that combine detailed dietary records, randomized trials of coffee components, and mechanistic laboratory work will help clarify whether and how coffee directly protects liver tissue and reduces cancer risk.
